My invention relates, in general, to overhead trolley systems and it has reference in particular to overhead trolley fixtures such as frogs, crossings and the like.
Under the present closely competitive operating conditions in trolley and trolley bus systems, maintenance of schedules and reduction of expense are two important factors. Failure of the overhead system is highly disruptive t 0 schedule maintenance, and to prevent it, periodic replacement of worn parts, such as frogs and crossings, is necessary. This entails the use of much equipment and the expenditure of much valuable time, in the case of the conventional l type of overhead iixture. Traffic is tied up by the tower Wagons necessary to out out a worn frog or crossing, valuable time is consumed, and bus and trolley car schedules are ruined. The actual cost of the repair parts may be small, but o the time and money involved in the replacement may be quite excessive.
In addition to the time and labor necessaryV One object, therefore, of my invention sto provide a trolley fixture for overhead trolley systems that shall be readily installed and easily and inexpensively maintained. f 354 Another object of my invention is to provide a trolley fixture having interchangeable wearing parts that shall be inexpensive and easy to manufacture.
A further object of my invention is toprovide a line of trolley fixtures that shall be readily adaptable to a number of different settings or operating conditions' using the same integral parts.
A still further object of my invention is to provide a line of trolley fixtures having renewable Wearing parts which are adjustable to a large number of angular settings.
Still another object of my invention is to provide a line of trolley xtures through which the trolley wire may be continuous, or in which it may be terminated, which may be readily installed and of which the Wearing parts may be easily replaced and largely interchangeable.
Other objects will in part be obvious, and in part appear hereinafter. My invention, accordingly,.is disclosed in the embodiments hereof shown in the accompanying drawings,` and comprises the features of construetion, combination of elements and arrangements of parts, which will be exemplified in the description hereinafter set forth, and in the scope of the application of Which will be indicated in the appended claims.
For a more complete understanding of the nature and scope of my invention, reference may be had to the .following detailed description taken l0 in connection with the accompanying drawings, in which;

4, and Y7; and
Fig. 13 is a sectional view of the seating mem- 40 ber taken along the line XIII- XIII of Fig. 12.
Referring particularly to Figs. l, 2, and 3, the reference numeral I0 denotes, generally, one form of trolley crossing embodying my invention. It comprises a main plate member II, a plurality of 45 trolley Wire seating members l2, adapted to align the intersecting trolley wires I3, and a plurality of renewable runner portions i4 and I5, disposed to guide a current collector (not shown) through the intersection. 50
The mainplate member II may be provided with'eyes I6 for securing it in position in the overhead: system. Trolley Wire recesses Il may be provided in the main plate member II by the upwardly sloping channels in which the trolley 55 wires I3 are disposed to be secured by any suitable means, such as the U-bolts I8 which may pass through arcuate slots 22 in the plate member II.
To maintain the trolley wires I3 in fixed relation, the seating members I2 may be provided with a longitudinal groove I9 as shown in Figs. 3 and 13, in which the trolley Wires I3 are disposed to lie. An offset positioning flange 20, which may be an integral part of the seating member I2, is adapted, in conjunction with the bolts 2l and the arcuate slots 22, to secure the seating member I2 to the main plate member II.
The renewable runner portions I4 and I5, which may comprise channel-like members having a closed beveled end 23, may be secured to the main plate II by offset positioning fianges 24, at least one of which is positioned in opposite relation to the positioning flange 2U of the trolley wire seating member I2, and bolts 2I passing through the arcuate slots 22 of the main plate member II. A spacing member 26 is adapted to relatively position the bolts 2|, and the U-bolts I3. The renewable runner portions I4 and I5 are disposed to provide, in conjunction with the central guide member 21, which may be positioned in any suitable manner such as by bolts 28, a substantially smooth path for a current collector.
To provide a smooth approach, the armored approach members 29 are secured about the trolley wire I3. These approach members may be constructed in any suitable manner, as from a flat strip of a conducting material, such as sheet copper, being formed into a U-shaped channel, and then crimped about the trolley wire.
Figs. 4, 5, and 6 show how the principles of the invention may be applied to a trolley cross-over of another type. The reference numeral 30 denotes generally a 90 degree cross-over having a main plate member 3l and a unitary renewable runner portion 32 provided with integral runners 33 and 34, a central guide portion 35 and integral offset positioning fianges 36.
This cross-over is also provided with trolley wire seating members I2 having positioning flanges 20 oppositely positioned with respect to the fianges 36 on the runner portion 32. The runner portion 32 is secured to the main plate member by means of bolts 31 while the seating members I2 are secured thereto by means of bolts 2I. Approach members 29 are also provided to be crimped about the trolley wire I3 to secure a smooth approach for a current collector.
As shown in Fig. 5, the trolley wires I3 may be terminated at the U-bolts I8, instead of being continuous as shown in Fig. 2.
Referring to Figs. 7, 8, and 9, the reference numeral 4D denotes, generally, a trolley frog embodying the same principles of the invention. It may comprise a main plate member 4I having eyes 42 for securing the frog in an overhead trolley system. The upwardly inclined trolley Wire channels 43, in the main plate member 4I, are disposed to accommodate the trolley wire I3, it being maintained in fixed relation by securing means, shown as U-bolts I8.
In this embodiment of my invention, a unitary runner portion 44 may be secured to the main plate member 4I by integral offset flanges 45 and bolts 46 passing through the main plate member. The positioning fianges 45 are disposed to be oppositely positioned to the integral flanges 20 which with the bolts 2I secure the trolley wire seating members I2 to the plate member 4 I.
From Fig. 10, which is a top plan view of the renewable runner portion 44, it may be seen that this portion may comprise a pair of channel-like intersecting guide members 41 and 48, and an integral central pan portion 49 on which a current collector (not shown) is disposed to ride as it traverses the frog. 'I'he adjacent ends of the guide members 41 and 48 are beveled at the junction end so as to provide a smooth transition for the current collector. The edges of the central pan portion 49 are disposed to be upturned forming. guiding vanes 5U and 5I to assist in guiding the current collector as it passes the intersection.
From the foregoing, it may be seen that in my invention I provide a line of trolley fixtures that not only have renewable wearing parts, which are largely interchangeable, but which are easy to manufacture and which are adustable so that a small number of parts only are required for a large number of different applications. Such a fixture is easily installed in an overhead system, and when once installed is easily and economically maintained. A minimum of time and equipment is necessary to renew worn parts, and as the runner portions are largely adjustable, only a small stock of fixtures is required to cover renewal parts for a large number of different angle intersections.
